i hated algebra as a teen and i now hate it as the parent of a teen. algebra is of satan.
this is part of why algebra is so demonic:
the sale price of a radio is 30% below the original price of the radio, but a 7 % sales tax is added to the sale price. betty’s total bill for her radio came to $97.54. what was the original price of the radio Betty bought on sale? (hint: let x be the original price of the radio. write an equation to represent the problem and then solve it.)
the answer is $130.23 but the problem is writing out the equation. oh how i hate algebra.
